Hi Ed,
Well put and concise--thanks.
However, you baffle me on one point (only one this time). I understand about prism size and internal scattering of light "rays." But, I do not quite see the relationship between scattering and the vignette (-ing).
A genuine vignette, it seems to me, should descibe the gradual falloff of light at the EDGES of the FOV, possibly due to too-small prisms or baffles, for example. I can't particularly correlate this to light scatter. Perhaps I am not understanding your text, but a sentence or two of clarification I will appreciate. Thanks.
Regards,
Dave.
